Degradation process of BasicVSR

[mrluin]

Hi,

Thanks for your great work!

I only know about the value kernel size and sigma, but I am not familar with Matlab. Could you provide python code of degradation process of BasicVSR, or provide some references? Thanks again.

For BIx4, we use MATLAB to resize the images: lq = imresize(gt, 0.25).

For BDx4, you can find the MATLAB script here.

@ckkelvinchan do you know a way to approximate the matlab resize?

Getting rid of the matlab dependency would be a great thing

I think I have seen the python code somewhere before, I can look for it.

Here, since you helped a lot with your repository. I thought I could lend a hand too.

Thank you! I will have a look at that.

Added in #507. Note that the implementation is not exactly the same as the MATLAB implementation, though the difference is small.
